I've just done a quick scan: both types cause locally written rules to fire, but almost all the pump'n'dump spam would be caught by standard SA rules and/or URIBLs. I'm uncertain whether this also applies to the marital aid spam: it triggers my "CYRILLIC" rule, which simply catches anything with a .ru or .su TLD unless its from one of my three Russian correspondents. So, no, I don't agree with you: SA is working just fine here. My local rule collection is largely stable, is changing very slowly and is averaging less than one misclassified ham per week - and I can easily fish that out of my quarantine area. Currently my spam load is around 15-20% of incoming mail, which is relatively low volume as I'm a private site. HTH Martin
